Question

(1-\sqrt{x})/1+\sqrt{x}

Answer 1

Answer:

$\frac{1 - 2 \sqrt{x} + x }{1 - x}$

Step-by-step explanation:

$\frac{1 - \sqrt{x} }{1 + \sqrt{x} }$

Rationalize the denominator by multiplying by it conjugate.

$\frac{1 - \sqrt{x} }{1 + \sqrt{x} } \times \frac{1 - \sqrt{x} }{1 - \sqrt{x} } = \frac{1 - 2 \sqrt{x} + x}{1 - x}$
